Harmonic Highlights:

  • The progression features a series of descending chromatic ii-V sequences (Gm7-C7, F#m7-B7, Fm7-Bb7), creating rapid, temporary shifts in tonal gravity.
  • Extensive use of tritone substitutions (e.g., D7 leading to Dbmaj7) and dominant cycling delays the final resolution to the Ab major tonic.
  • Monk utilizes altered dominant tensions (Ab7#5, B7#11) to create melodic dissonance while maintaining functional root movement.
  1. Improvisation Focus: Navigating descending chromatic ii-V cells using smooth voice leading.

  2. Difficulty Rating: 4/5: The rapid sequence of non-diatonic modulations and sophisticated substitution patterns requires advanced harmonic navigation and vertical precision.
